Pool Watch

Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are
in trouble.A report says that on average 15 people drown in British pools each year,but
many more suffer major injury after getting into difficulties.Now a French company has
developed an artificial intelligence system called Poseidon that sounds the alarm when it
sees someone in danger of drowning.
When a swimmer sinks towards the bottom of the pool,the new system sends an alarm
signal to a poolside monitoring station and a lifeguard's pager（呼机）.In trials at a pool in
Ancenis,near Nantes,it saved a life within just a few months,says Alistair McQuade,a
spokesman for its maker,Poseidon Technologies.
Poseidon keeps watch through a network of underwater and overhead video cameras.
Al software analyses the images to work out swimmers' trajectories（轨迹）.To do this
reliably,it has to tell the difference between a swimmer and the shadow of someone being
cast onto the bottom or side of the pool.
It does the same with an image from another camera viewing the shape from a different
angle.If the two projections are in the same position,the shape is identified as a shadow
and is ignored.But if they are different,the shape is a swimmer and so the system follows
its trajectory.
To pick out potential drowning victims,anyone in the water who starts to descend
slowly is added to the software's"pre-alert"（预先警戒）list,says McQuade. Swimmers
who then stay immobile on the pool bottom for 5 seconds or more are considered in danger
of drowning.Poseidon double-checks that the image really is of a swimmer,not a shadow,
by seeing whether it obscures（使模糊）the pool's floor texture when viewed from overhead.
If so,it alerts the lifeguard,showing the swimmer's location on a poolside screen.
The first full-scale Poseidon system will be officially opened next week at a pool in High
Wycombe,Buckinghamshire.One man who is impressed with the idea is Travor Baylis,
inventor of the clockwork（时钟装置）radio. Baylis runs a company that installs swimming
pools-and he was once an underwater escapologist（脱身杂技演员）with a circus（马
戏团）."I say full marks to them if this works and can save lives,"he says.

How does Baylis look at the Poseidon system?
A:He thinks it is too expensive.
B:He thinksi t is a good system.
C:He thinks it is not efficient enough.
D: He thinks it is as good as the British pool watch system.

Pool Watch

Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble.The
Royal Society for the Prevention of Accidents says that on average 15 people drown in British poois each
year,but many more suffer major injury after getting into difficulties.Now a French company has developed
an artificial intelligence system called Poseidon that sounds the alarm when it sees someone in danger of
drowning.
When a swimmer sinks towards the bottom of the pool,the new system sends an alarm signal to a pooi-
side monitoring station and a lifeguard's pager. In trials at a pool in Ancenis,near Nantes,it saved a life
within just a few months,says Alistair McQuade,a spokesman for its maker,Poseidon Technologies.
Poseidon keeps watch through a network of underwater and overhead video cameras.Al software
analyses the images to work out swimmers'trajectories.To do this reliably,it has to tell the difference be-
tween a swimmer and the shadow of someone being cast onto the bottom or side of the pool."The underwater
environment is a very dynamic one,with many shadows and reflections dancing around,"says McQuade.
The software does this by"projecting"a shape in its field of view onto an image of the far wall of the
pool.It does the same with an image from another camera viewing the shape from a different angle.If the
two projections are in the same position,the shape is identified as a shadow and is ignored.But if they are
different,the shape is a swimmer and so the system follows its trajectory.
To pick out potential drowning victims,anyone in the water who starts to descend slowly is added to the
software's "pre-alert" list,says McQuade.Swimmers who then stay immobile on the pool bottom for 5
seconds or more are considered in danger of drowning. Poseidon double-checks that the image really is of a

radio.Baylis runs a company that installs swimming pools一and he was once an underwater escapologist with
a circus." I say full marks to them if this works and can save lives,"he says.But he adds that any local
authority spending ￡30,000-plus on a Poseidon system ought to be investing similar amounts in teaching
children to swim.

Which of the following statements about Travor Baylis is NOT true?
A:He runs.
B:He invented the clockwork radio.
C:He was once an entertainer.
D:He runs a company.
